Definitions
- the invention relates to a process for the sterilization of surfaces, in particular ofmaschinesgutobervid, for example surfaces of packaging webs, hollow bodies or the like, according to which short-wave electromagnetic radiation acts on the surface.
- Short-wave electromagnetic radiation in the context of the invention means radiation which regularly adjoins the visible spectrum in the short-wave range, ie is generally equipped with wavelengths below 400 nm.
- the short-wave electromagnetic radiation in question is generally UV radiation in the wavelength range between about 170 nm to 380 nm.
- the sterilizing effect of such short-wave electromagnetic radiation is well known, which is why UV radiation for disinfecting treatment of water, air and surfaces is used (see DE 10 2004 032 861 A1).
- UV lamps can be used, for example, for the disinfection of air streams.
- the drinking water treatment with UV radiation the bacterial count is reliably reduced in the water and depending on the dose, so that an addition of chemicals is basically not required.
- UV radiation below 200 nm is so shortwave or energetic that it is completely absorbed by molecular oxygen.
- the molecular oxygen (0 2 ) is split into two free oxygen radicals (20), which each react with another molecule of oxygen (O 2 ) to ozone (O 3 ) on.
- UV radiation with a wavelength below 200 nm can only propagate in a vacuum (so-called vacuum UV radiation).
- the invention aims to provide a total remedy.
- the invention is based on the technical problem of further developing such a method for the sterilization of surfaces so that the germicidal or sterilizing effect of the short-wave electromagnetic radiation impinging on the surface is improved compared to previous approaches.
- the invention proposes in a generic method for the sterilization of surfaces, in particular ofmaschinesgutoberfest that the short-wave electromagnetic radiation is conducted from a radiation source to the surface through a transmission medium tuned to the radiation.
- a special transmission medium between the radiation source and the surface is used.
- this transmission medium is distinguished by the fact that it corresponds to a reduced absorption of the electromagnetic radiation passed through compared to, for example, atmospheric air under normal pressure at this point.
- the transmission medium thus favors the unhindered passage of the short-wave electromagnetic radiation or reduces the absorption of the radiation on its way from the radiation source to the surface to be treated or packaging material surface.
- the transmission of electromagnetic radiation, the transmission is improved over the situation in atmospheric air.
- the invention proposes as a transmission medium, a gas, in particular inert gas, and / or a gas mixture and / or a liquid / gas mixture.
- the gas mixture or liquid / gas mixture predominantly contains no atmospheric air.
- a further second component is added, which fills more than 50% by volume of a volume passed through the radiation, usually even more than 80% by volume.
- This further second component has a lower absorption of the short-wave electromagnetic radiation compared to the atmospheric air (under normal pressure).
- the gas mixture or liquid / gas mixture with air as the first component and the described second component with lower absorption is overall designed such that the transmission of the electromagnetic radiation from the radiation source to the surface is favored.
- said second component in gaseous and / or liquid form for example, the air and / or the surface to be treated can be fed directly.
- the second component in liquid Form it is advisable to heat the surface to be treated. Because in this way the evaporation rate of the second component can be increased.
- small amounts of the second component are often sufficient in liquid form.
- the invention recommends as a second component argon or other comparable noble gases such as helium, xenon, krypton or even nitrogen. If one considers that the volume ratio of the aforementioned gases from liquid to solid state is several hundred, for example argon 700, then for the complete filling of for example one liter bottle with argon only 1.4 ml of liquid argon is needed.
- the liquid used as a second component usually evaporates in the short term in a period between 1 and 5 sec ..
- the volume of air initially present in the hollow body or the liter bottle in the example may be predominantly displaced.
- the evaporation rate is then increased when the surface to be disinfected is heated.
- the aforementioned gases or protective gases can also be used directly and solely as a transmission medium in (initially) liquid and (then) gaseous form. Then, the transmission medium is not primarily a gas mixture, but only the gas or inert gas.
- the invention exploits that the second component described above or used at this point gases such as argon, helium, xenon and krypton as noble gases or nitrogen generally act as protective gases and the propagation of short-wave electromagnetic radiation in the transmission medium favor.
- gases such as argon, helium, xenon and krypton as noble gases or nitrogen generally act as protective gases and the propagation of short-wave electromagnetic radiation in the transmission medium favor.
- the transmission medium is composed essentially of air as the first component and a predominant shielding gas in liquid or gaseous form as a second component. In principle, however, the transmission medium may also be just the gas or inert gas.
- the invention makes use of the fact already described above that the propagation of electromagnetic radiation at wavelengths, for example below 220 nm in air under normal pressure by absorption in or on oxygen molecules is limited. This is because the oxygen molecules undergo the previously described splitting into atomic oxygen with subsequent ozone formation. This effect is within the scope of the invention Part desired, because it supports the germicidal effect of short-wave electromagnetic radiation through the formation of ozone.
- the second component in the gas mixture or liquid / gas mixture or the protective gas for the representation of the transmission medium ensures that the short-wave electromagnetic radiation is not (more) absorbed as strongly as in pure atmospheric air. This allows the protective gas, which is penetrated by the radiation in question with much higher intensity than a comparable volume of air (at atmospheric pressure). In this way, the intensity of the electromagnetic radiation on the surface to be sterilized is increased and consequently the sterilizing effect is improved as desired.
- argon it applies to argon that up to wavelengths of about 170 nm virtually no transmission losses of short-wave electromagnetic radiation are observed. Consequently, argon can be regarded as the protective gas or second component in the gas mixture or liquid / gas mixture in addition to the inevitable existing atmospheric air as the first component as optimal.
- the transmission medium in addition to the atmospheric air and the inert gas in gaseous or liquid form additionally contains water and / or water vapor.
- the water vapor is generally admixed with the transmission medium and / or fed directly to the surface to be sterilized or to be disinfected.
- the temperature of the surface is adjusted so that the water vapor or the water condenses on the surface.
- the temperature of the surface should be adjusted evenly to provide a homogeneous water wetting of the surface available.
- the temperature of the surface is set such that variations of less than ⁇ 5 ° C, especially less than ⁇ 2 ° C, over the entire surface are observed.
- the surface to be sterilized with the aid of water vapor is wetted over the entire surface and the water vapor can contribute in addition to the sterilization by the short-wave electromagnetic radiation. Because by the UV radiation in question OH radicals are formed in the water or water vapor, kill the microbes, thus microbiocidal act.
- the general procedure is that the water or water vapor condenses to microdroplets, for example, have diameters in the micrometer range.
- the water droplets in question preferably form on germs, which function as condensation nuclei in this context.
- the desired OH radicals are formed exactly locally where they are needed, namely at the site of the germs. It is therefore generally not necessary for the OH radicals formed to first have to diffuse to the ones in order to kill them there.
- a further advantage is that the OH radicals formed by the radiation in the liquid drop can diffuse a few tenths to a few millieth and thus can also act in places that are not directly irradiated by the radiation. Such locations may be, for example, undercuts or threaded areas in a cap.
- the disinfection time can be drastically reduced, for example by a factor of 5. If one goes from a desired germ reduction, for example, by 5 decades (reduction by a factor of 10 5 ), which are microbiologically can be determined, so in the context of the conventional procedure, ie, resorting to a UV radiation source, a certain disinfection time of, for example, one minute in atmospheric air is needed.
- a UV radiation source for example, a low-pressure mercury vapor lamp or an excimer radiator or another suitable radiation source which emits quanta down to 170 nm may be used.
- This treatment time of one minute can be reduced to about 12 seconds and observe the previously mentioned factor 5, if the UV radiation from the radiation source to the surface is not atmospheric under otherwise identical experimental conditions and the same desired germ reduction by 5 decades Air passes, but the atmospheric air is added as the first component argon or an argon-nitrogen mixture as the second component. This may be realized so that a mixing ratio between the first component and the second Component in the range of about 20 vol .-% to 80 vol .-%, based on the total volume of the transmission medium, is present.
- the above-mentioned time reduction for the disinfection by a factor of 5 can be increased by a factor of 3 again, so that one observes a time reduction by a factor of 15 on the bottom line. Ie. instead of an irradiation period of 1 min. only 4 seconds are needed under otherwise identical conditions.
- This additional reduction of the treatment time or irradiation time by a factor of 3 can be achieved by adding water or steam to the transmission medium.
- the amount of water added is just enough that the condensing fraction of the moisture amount between 100 pg to 300 pg.
- this additional addition of water or water vapor in the transmission medium causes the sterilizing effect of the short-wave electromagnetic radiation or UV radiation used to be increased once more.
- the invention makes use of the fact that OH radicals are formed by the energy of the short-wave electromagnetic radiation in the water.
- This effect is known in principle (see the article by Moogega Cooper and others "Decontamination of Surfaces from Extremophilic Organisms Using Nonthermal Atmospheric Pressure Plasmas", IEEE Transactions on Plasma Science 2008, pp. 1 to 5). That is, the low addition of moisture to the otherwise dry atmosphere promotes the microbial effect of UV radiation on the surface to be treated.
- the formation of OH radicals in the water is particularly pronounced at short wavelengths in the range of 200 nm.
- the formation of OH radicals in water is reduced at longer wavelengths in the range of 250 nm.
- argon is used as the second component in addition to air in the gas mixture or argon exclusively as a transmission medium and this favors the transmission up to wavelengths of about 170 nm, particularly low disinfection times in the described combination (addition of argon and steam) observed.
- FIG. 1 shows a device for the sterilization of surfaces, in this case in or on a hollow body
- FIG. 2 shows a variant of FIG. 1,
- Fig. 3 shows the device for the sterilization of surfaces, in the present case of packaging webs and
- the device in a further variant for sterilizing the surfaces of a cap as a hollow body, which has been dispensed with the representation of the thread located in the cap.
- hollow bodies 2, 10 can be treated on their surfaces in the manner to be described below.
- the hollow bodies 2, 10 may be cans, cans, bags, bottles 2, cups or caps 10, as shown in FIG. 4a.
- FIGS. 1 and 2 A sterilizing treatment of surfaces of the hollow body 2 or the bottles 2 in the example case is shown in FIGS. 1 and 2.
- Fig. 3 is concerned with the disinfecting treatment of surfaces of the packaging web 7.
- Fig. 4 is directed to the treatment of surfaces inside or outside of caps 10 which, for example, follow this treatment to close the bottles 2 or be used by other hollow body 2, 10.
- a short-wave electromagnetic radiation source 9 which is designed as a UV radiation source or UV emitter 9.
- the UV radiator 9 is not expressly shown.
- the same or comparable procedure is used, as is fundamentally explained by the individual method steps according to FIGS. 4 a, 4 b and 4 c.
- the surface to be treated is first treated in a first step with water or steam.
- the water may be supplied directly via a dip tube 8 for water vapor.
- the water or the water vapor wets the surface to be treated, in the example according to FIG. 4 a the interior of the cap 10 there.
- the cap 10 in question or the surface to be disinfected is subjected to a transmission medium.
- the water or the steam can also be admixed with the transmission medium.
- the exemplary embodiment is a gas mixture.
- the gas mixture is composed of atmospheric air as the first component and argon as another second component.
- nitrogen or an argon / nitrogen mixture can also be used as the second component.
- the second component causes the transmission medium in question to be tuned in total to the short-wave electromagnetic radiation or UV radiation emitted by the UV radiator 9. This is because the transmission medium in question has a lower absorption for the UV radiation than atmospheric air, which is usually used at this point.
- the transmission medium can of course also act in pure form, for example as a protective gas for the electromagnetic radiation guided thereby. Then appropriate foreclosure measures are required to prevent mixing with the surrounding air. in the Generally, however, there is - inevitably - an air mixture instead, so that subsequently throughout a gas mixture or liquid-gas mixture is mentioned.
- the transmission medium present in the interior of the cap 10 the absorption of the UV radiation emitted by the UV radiation source 9 is reduced compared to a comparable filling of the cap 10 with atmospheric air. This increases the radiation intensity at the surface to be treated. Consequently, the UV radiation dose is increased and improves the germicidal effect, as has already been explained in the introduction.
- the surface to be treated it is advisable to adjust the surface to be treated to a certain temperature in order to achieve a homogeneous wetting of the surface with the introduced water vapor.
- the temperature of the surface will be adjusted uniformly over the entire surface in such a way that, for example, temperature deviations in the range of at most ⁇ 2 ° C. over the entire surface are observed.
- the setting of the surface temperature of the surface to be disinfected by means of surface heating is also favorable against the background that, as shown in FIG. 2 not only a water wetting is possible and carried out, as shown in Fig. 4a with the local dip tube 8 for Steam is shown.
- the transmission medium can also as Be designed liquid / gas mixture. Then, unchanged atmospheric air is used as the first component or is inevitably present.
- the further second component is a liquid which, after it has evaporated, forms a protective gas which exhibits a reduced absorption of the short-wave electromagnetic radiation compared with atmospheric air.
- the hollow body 2 may be a second liquid component 4, which is introduced into the interior of the hollow body 2 (see Fig. 2). It is conceivable in this context, for example, to inject into the hollow body 2 a few milliliters of liquid argon or liquid nitrogen via a dip tube 1 (or another dip tube).
- the questionable second liquid component 4 or the protective gas 4 introduced in liquid form evaporates completely in a short time (less than 5 sec.) And fills the hollow body or the bottle 2 predominantly.
- the described evaporation is favored even in the event that the hollow body or the bottle 2 has a certain (increased) surface temperature of for example 40 ° C or 50 ° C.
- FIG. 1 shows how the gaseous second component or the protective gas is introduced in gaseous form into the bottle 2 via the dip tube 1 and the air present there is almost completely displaced.
- the UV radiation source 9 are similarly introduced into the hollow body 2 for the purpose of disinfection, as is shown in principle in Fig. 4c.
- a guide 6 which basically serves to lead, for example, from the dip tube 1 or from the longitudinal tube 5 via local outlet openings 11 emerging transmission medium or the gas mixture in the example.
- the UV radiation source 9 radiates through the curtain formed by the guide 6 or the two guide plates 6 arranged on both sides of the longitudinal tube 5.
- water or water vapor can be applied to the local packaging web 7 again.
- the Guide 6 are brought to a temperature which is, for example, 5 ° C higher or even higher than the temperature of the packaging web 7 in order to realize a condensation of water or water vapor on the surface of the packaging web 7 in any case.
- the packaging web 7 is designed as a web-shaped packaging material, for example as a plastic web, film web, web of composite materials etc. With the help of such packaging webs 7, for example, individual containers can wrap around and the hollow body forming the container can be summarized. It is often necessary to sterilize the packaging web 7 in question as described.
- the water or water vapor can basically be added to the transmission medium. Then, for example, one will proceed as shown in FIG. 1 or also in FIG. 2 or 3. But it is also possible to make the admission of the surface to be disinfected in several steps. Then you will first act on the surface with water or steam, as shown in Fig. 4a. Subsequently, the surface is then rinsed with the transmission medium or filled at this point hollow body 2 respectively the cap 10 or bottle 2 filled with the transmission medium in its interior. Thereafter, only the treatment with the UV radiation source 9 takes place. As already explained, the steps of the water vapor and transmission medium supply can of course also be reversed. In addition, both steps can also be combined.
